Preparation of Y-Zr-Hf,Y-Zr-Nb Ternary Diffusion Couples and Phase Diagrams Determination
摘要
Work has been done in preparing ternary diffusion couple containing one rare earth element.Though rareearth is highly reactive,we have successfully prepared two ternary diffusion couples containing yttrium by meansof special technique.By using electron microprobe analysis(EMPA),the two isothermal sections of Y-Zr-Hfand Y-Zr-Nb ternary systems at 1273K have been determined.The section of Y-Zr-Hf system consists ofthree one-phase regions,three two-phase regions and one three-phase region.And that of Y-Zr-Nb systemconsists of two one-phase regions and one two-phase region.The effeet of some factors on EMP measuring ac-curacy was also discussed.
